Mitsubishi Electric MELSEC iQ-R-R00CPU - Refresh Mode

48
1 RUNNING A PROGRAM
1.3 Data Communication and I/O Processing
Refresh mode
The CPU module performs I/O processing collectively at a specified timing.
The timing of the input refresh and output refresh follows the specified refresh timing setting.
Outline of the processing
The following describes the details of the refresh mode.
*1 The remote input refresh area indicates the area to be used when refresh is set to the input (X) in CC-Link IE Controller Network, CC-
Link IE Field Network, CC-Link IE Field Network Basic, MELSECNET/H, or CC-Link.
*2 Data in the engineering tool input area can be turned on or off by the following:
 Test operation of an engineering tool
 Writing data from the network module
 Writing data from an external device using SLMP
*3 Data in the output (Y) device memory can be turned on or off by the following:
 Test operation of an engineering tool
 Writing data from the network module
 Writing data from an external device using SLMP
Item Description
Input refresh At a specified timing (at END instruction execution or before specified program execution), input data are collectively
read out from the input modules (1), the OR processing with the engineering tool input area and remote input refresh
area is executed, and then the data are stored in the input (X) device memory.
Output refresh At a specified timing (at END instruction execution or before specified program execution), data in the output (Y)
device memory (2) are collectively output to the output module.
